8dBi Gain 470-862MHz TV Antenna

Product introduction

1. High Gain 8dBi for Weak Signal Areas

Delivers 8dBi gain across UHF band (470-862MHz), significantly improving TV signal reception in rural, suburban, or fringe areas where signals are weak.

2. Excellent Directivity & Front-Back Ratio

With a front-back ratio ≥14dB, this antenna effectively rejects interference from the rear and sides, providing cleaner picture and more stable reception.

3. Low VSWR for Efficient Signal Transfer

VSWR ≤1.5 ensures minimal reflected power and maximum power transfer from antenna to TV, reducing signal loss and ghosting.

4. Robust Power Handling

Supports maximum input power of 50W – suitable for passive reception as well as active/powered TV systems without risk of damage.

5. Standard 75Ω Impedance

Matches standard TV coaxial cables (RG6, RG59) and TV tuners, ensuring plug-and-play compatibility with most home and commercial TV systems.

Application Scenarios

●Home Digital TV Reception – Replace indoor rabbit ears with outdoor UHF antenna for free-to-air HD channels.

●Rural & Remote Areas – High gain pulls in distant TV towers where signal is weak.

●RV & Camping – Mount on RV roof to watch local channels while traveling.

●Cabin & Vacation Home – No cable subscription needed – get over-the-air TV.

●Commercial Display – Bars, hotels, and waiting rooms needing free local channel distribution.

FAQ

Q: What frequency band does this antenna cover?

A: UHF band from 470MHz to 862MHz – covers most digital terrestrial TV channels worldwide (except VHF low band).

Q: What is the gain?

A: 8dBi, which provides strong directional reception for weak signal areas.

Q: Is this antenna indoor or outdoor?

A: Designed for outdoor mounting (roof, mast, or attic) for best performance.

Q: What is the VSWR?

A:≤1.5, indicating excellent impedance matching and low signal reflection.

Q:Can I use it for analog TV?

A: Yes, it works for both analog and digital (DVB-T/T2, ATSC, ISDB-T) TV signals within the UHF band.

Q: What is the front-back ratio?

A: ≥14dB, meaning strong rejection of signals coming from behind the antenna, reducing interference.
